Requires 1 button.

Photo shows about 1 inch of garter stitch on the back piece at the top edge that folds over as a flap, but it is not listed on the pattern. Recommend adding 1 inch to account for the error. Pattern also does not give instructions for button hole, but that should be in the middle of the garter stitch band.

In Lion Brand Wool-ease Thick and Quick, could just be completed with 2 skeins on gauge. May need to shorten the strap depending on your gauge.
